Earlier this week TrendForce said this year’s iPhone models could include Apple Pencil support, and now another report from Taiwanese publication Economic News Daily is out backing that up, citing “industry insiders.”

EDN’s sources echo TrendForce, but go on to note which models are getting in on the stylus action. They say Apple Pencil support will be limited to the 5.8-inch and 6.5-inch AMOLED screen models, while the 6.1-inch LCD iPhone won’t support Apple’s stylus.

All of this points to Apple‘s apparent strategy to increase the number of its devices that support the Pencil; since its debut in 2015, only the higher-end iPad Pros did so, but earlier this year, Apple extended this to its latest, less-premium iPad line, too.

It’s currently unclear if Apple would release a smaller variant of the Pencil similar to the S-Pen that comes with Samsung’s Note line of smartphones, given the current ones could be too big for efficient use with smaller screens in some situations.

As display sizes have become larger than what they were in the past, the potential for the Pencil can help in enhancing the user experience as one can use it for drawing as well as digital signatures.

Released almost three years ago, Apple’s belated answer to Samsung’s universally praised S Pen hasn’t received as much as a facelift since November 2015.
